MS-3552

A 35-year-old woman visits her GP after observing alterations in her facial appearance. She realized that the left side of her face was sagging that morning, and she couldn’t entirely shut her left eye, and her smile was uneven. She is healthy and not taking any other medications. During the examination of her facial nerve, you observe that the left facial nerve has a complete lower motor neuron paralysis. What is the probable reason for this?
